Explanation:

Plastic takes time to degrade which means it has great longevity. Plastic does not break as easily as glass or other materials. It lasts long and offers great service. Plastic storage containers offer greater flexibility than any other packaging materials.

Explanation:

[tex]workdone = force \times distance \\ W = (2.6 \times {10}^{ - 4} ) \times (3.7 \times {10}^{ - 3} ) \\ W = 9.62 \times {10}^{ - 7} \: joules[/tex]

The formula W = Fd, where W is the amount of work done, F is the force, and d is the distance, is used to determine how much work is done on a particle when it is pushed by a force. The force and distance in this issue are 2.6 10-4 newtons and 3.7 10-3 metres, respectively.

We add the force and distance together to determine the work done: 9.62 10-7 newton-meters are equal to W = 2.6 10-4 newtons x 3.7 10-3 metres. The response must be presented using the appropriate scientific notation and significant numbers.

The solution should include three significant figures, just like the numbers in the problem, which have three. Therefore, 9.62 10-7 newton-meters is the correct answer.

This response uses appropriate scientific language.notation because the exponent is a negative power of 10 and the coefficient ranges from 1 to 10. In conclusion, the particle underwent work from the force of 9.62 10-7 newton-meters. This response uses the appropriate scientific notation and the correct number of significant digits.

Answer:

Terracing.

Explanation:

Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Soil conservation can be defined as the use of various techniques so as to prevent the loss of the top most later of the soil and protecting it from degradation. Thus, the fertility of the soil is maintained.

The soil conservation method in which mountain slope is cut into step is terracing.

Answer:

Final pressure = 1848.36 Torr

Explanation:

Given that,

Initial volume, V₁ = 5.2 L

Initial pressure, P₁ = 782 Torr

Initial volume, V₂ = 2.2 L

We need to find the final pressure. We know that the relationship between pressure and volume is given by :

[tex]P\propto \dfrac{1}{V}\\\\\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{782\times 5.2}{2.2}\\\\P_2=1848.36\ torr[/tex]

So, the final pressure is equal to 1848.36 Torr.

Answer:

70/100 X 2000 = 1400 tonnes of iron.

Explanation:

take the percentage of iron oxide and divide with overall amount of iron oxide using 2000 tonnes of hematite ore. 1400 tonnes of iron will be produced. this is not the percentage. if you want the percentage of iron produced just divide.

70/100 x 200 = 1400 tonnes of iron

percentage of iron produced = 70/1400 x 100 = 5 % of iron produced from 70% of iron oxide in 2000 tones of hematite ore

Answer:

4 M

Explanation:

Molarity refers to the molar concentration of a substance (solution). It can be calculated by using the formula below:

Molarity (M) = number of moles (n) ÷ volume (V)

According to the information provided in this question;

V = 0.4 liter

n = 1.6 moles

Molarity = n/V

Molarity = 1.6/0.4

Molarity = 4 M

The pairs of solutions produce a precipitate when combined are  NH4Cl and AgNO3. Therefore, option B is correct.

Chemical precipitation is the process of turning a liquid into a solid by either making the liquid insoluble or making it extremely saturated.

The chemical reaction between potassium chloride and silver nitrate, in which solid silver chloride is precipitated out, is one of the best examples of precipitation reactions. This is the precipitation reaction's byproduct, the insoluble salt.

Thus, The pairs of solutions produce a precipitate when combined are  NH4Cl and AgNO3, option B is correct.

Answer:

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. ... Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine

Answer:

1.67 × 10⁻¹⁰m is the answer.

Explanation:

Given,

4 × 10⁻⁷m thick

2400 atoms thick

therefore 1 atom,

Diameter = 4 × 10⁻⁷/2400

d = 4000 × 10⁻¹⁰/2400

d = 1.67 × 10⁻¹⁰m

∴ diameter of 1 gold atom (3 significant figures) = 1.67 × 10⁻¹⁰m

Answer:

It has to do with increasing the entropy of the universe.

Explanation:

The modern definition of entropy is that it is the extent to which a system is able to disperse its energy. Energy (such as heat!) likes to spread itself out, so that as many states as possible are occupied with the least amount of energy.

Answer:

B. The reaction would shift to produce more O2 and SO2-

Explanation:

This is because the forward reaction is exothermic.

The correct answer is option B. The reaction would shift to produce more O2 and SO2-

A decrease in temperature will cause the equilibrium to shift to favour the exothermic reaction. Therefore the reverse reaction rate will decrease sharply, and then gradually increase until equilibrium is re-established.

If the temperature is increasing, a product is being added to the equilibrium, so the equilibrium shifts to minimize the addition of extra product: it shifts back toward reactants.

D. Quantitative

Explanation:

Quantitative observation deals with numbers, or amounts.

Qualitative observation deals with de- scriptions that cannot be expressed in numbers.

Answer:

Right

Explanation:

The given parameters are;

The soluble sulfate formed by the metal, M = M₂SO₄

In the galvanic cell formed by the metal M, we have;

The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M

The concentration of M₂SO₄ in the right half cell = 5.00 M

In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated

In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode

Therefore;

The electrode which will be positive is the electrode in the right half cell.

Arrhenius acid increases the concentration of hydrogen ion in an aqueous solution and Arrhenius base increases the concentration of hydroxide ion in an aqueous solution.

Arrhenius acid dissociates in aqueous solution to form hydrogen ion. In aqueous solution Arrhenius acid increases the concentration of hydrogen ions.  

Arrhenius base dissociates in aqueous solution to form hydroxide ion. In aqueous solution Arrhenius base increases the concentration of hydroxide ions.

In aqueous solution of hydroxide ions bases dissociates. Greater the concentration of base means greater the concentration of hydroxide ion. If hydroxide ion concentration is more then pH will be less.

Thus, we can say that Arrhenius acid increases the concentration of hydrogen ion in an aqueous solution and Arrhenius base increases the concentration of hydroxide ion in an aqueous solution.
